SPRING-SEAT.

SPECIFICATION forming part of Letters Patent No. 536,725, dated April 2,1895.

I Application filed August 28, 1894. Serial No. 521,481. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE E. HOWARD, a citizen of the United States,and a resident of St. Louis, State of Missouri, have invented certainnew and useful Improvements in Spring- Seats, of which the following isa specification.

My invention relates to spring seats,.and has special reference to themeans employed to support the spiral springs used therein, and to retainthem firmly in position within the seat frame.

Where spiral springs are held in place by tie bands, either of metal orwebbing, there is a liability of the springs becoming detached from thebands, and falling over when compressed. If the springs are heldtogether by links, the breaking of a single link is apt to derange theentire series of springs, thus rendering the seat unfit for use untilrepaired. I prevent this liability by making the top support of thespring an integral part of the spring itself, the wire forming the uppercoil of the spring being so bent as to form an elongated extension,secured, at its end, to the seat frame, as will be hereinafter morefully set forth and described.

In the drawings: Figure 1, is a plan view of my improved spring seatshowing the springs, the cap plates, and the webbing which covers thesprings and plate. Fig. 2, is a vertical cross section of the seatframe, drawn on line 00, 0c, of Fig. 1. Fig. 3, is a top view of thespiral spring, showing the extension formed thereon. Fig. A, is avertical cross section of one of the bars of the seat frame, showing oneof the improved springs, and cap plate attached thereto, and a portionof the supporting cross bar on which the spring rests.

In the drawings like letters refer to like parts.

A, is the seat frame, and B, the cross bars, on which the springs rest,secured thereon.

G is the spiral spring, with the extension support and the extensionsupport is made from the same wire as the spring and this is done bycontinuing the wire of the top coil out in nearly a straight line andthe plane of the coil bent but slightly downward to form an arm O',thenbent at right angle to form the intermediate connecting part 0'', andthen turned back at right angle to form the arm 0" with its end securedto the upper coil of the spring. This extension support is secured tothe seat frame by staples, or otherwise, passing over the intermediatepart 0 5 5 as shown in Figs. 1, 2, and 4. Through this support thespring is held securely in place, and all tendency on the part of thecap plate to sag between the spring and the seat frame is prevented; andthat each spring is inde- 6o pendently provided with an extensionsupport so that each may be individually removed and replaced withoutdisturbing any of the others.

The cap plate D, is preferably formed of sheet metal, and secured to thespring extension and extends from the seatfrarne to, and slightlybeyond,the top coil of spring 0. The free end of the plate is slightly curveddownward so as to form a rounded edge, thus preventing the metal fromcutting the webbing or the upholstery which covers it. These cap plates,which extend over the springs from each side of the seat frame, aresufliciently separated at their ends in the center of the seat to allowfree play to the cap plates when the springs are compressed.

A The webbing E, covering the cap plates,is

secured at its ends to the seat frame. It serves to give the propershape to the spring section and to prevent the upholstery from being cutby contact with the metal plate.

What I claim as new and of my own invention, for which I ask LettersPatent of the United States, is

In a spring seat, the combination of the seat frame A, and springs 0within the frame each of said springs having the wire of its top coilcontinued outward in about a straight line GEO. E. HOWVARD.
